What You’ll Need
Before you can get into painting your bike you need to get the bike ready for it. Meaning, you will require a set of tools to take apart the bike. This means taking off the wheels and stripping it down to the bare frame.
At most, you will need a few screwdrivers and wrenches. If you don’t have a proper toolset you can easily find a suitable option at a general hardware store.
Once disassembled, it is a good idea to sand down the individual parts. This creates a fresh surface for the paint to adhere to for a quality paint job.
Additionally, you may find that portions of the paint can not be removed with simple sandpaper. If you run into this problem then a paint stripper can come in handy.
Furthermore, grease is another substance that should be cleaned off of the bike. It has a slippery texture that acts as a barrier between the paint and the bike. Removing the grease with a degreaser, glass cleaner, or white spirits is the way to clean the surface.
Beyond these removal substances and materials, you will need to apply masking tape to block off the bike. The masking tape helps keep certain parts of the motorcycle stain-free; simply remove them after painting to have a cleaner look overall.
Determining what type of paint to use is a simple matter of finding paint that adheres to metal. Of course, there are paints that are specifically formulated for bike frames, but car paint or any other metal-compatible paint is alright.
As long as your paint is able to stick to metal surfaces, you don’t need to take much else into account. The most significant decision in choosing the bike paint is what finish and color you want.
Finishes range from matte to glossy varieties that each bring a different look and texture to the bike frame. When picking your paint, it is recommended to use one manufacturer for every color used. This is to guarantee the finish is consistent throughout the bike.
Now that you have chosen your paint, all that’s left is to apply it. There are a couple of methods to apply the paint to the frame. Spraying it on is the preferred method as it evenly coats the surface.
As to how the paint is sprayed on, these are the methods you can use to get a consistent-looking, high-quality paint job.
Using an airbrush to paint a bike frame involves many moving parts but gives a beautiful, custom look to your bike. A compressor, as well as the airbrush gun itself, are two additional requirements you will need.
To find a suitable compressor to spray the paint, look for one that has a working pressure of one and a half to three bars. This is enough to eject the paint evenly from the airbrush nozzle.
Also, airbrush guns vary in their compatibility with certain kinds of paints and a model that can handle paint is the obvious choice here. Another consideration of the airbrush gun is the seals inside the nozzle. These should be solvent-resistant, so they don’t break down.
Additionally, airbrush paint is not thick enough to act as a protective layer on your bike. This is because it needs to be thinned to have an even distribution from the nozzle of the airbrush.
Since we are working with bike paint, you will need to thin out the paint to make it compatible with the gun. After getting the airbrush gun and paint ready, you can begin the painting process.
Hold the gun about 25 cm away from the bike frame. As the airbrush ejects paint in a thin mist, it is easy to cause “paint noses” if it is too close to the surface.
Furthermore, multiple passes of the gun over the bike frame are necessary to build up the paint slowly. Try to keep the same motion when doing your passes for a consistent look overall. This helps increase the durability of the paint while delivering the correct finish once the paint dries.
Why Use An Airbrush?
Applying paint with an airbrush involves some additional work, so why is it used by many? Well, the extra work serves as an advantage when painting a bike.
For those who are looking for a truly custom paint job, the mixing of the paint opens a world of possibilities. You can choose how much paint is loaded into the airbrush gun, giving you the freedom to create your own shades and colors.
Mixing and fine-tuning colors on practice surfaces can get you the exact shade you are looking for. So, if you want a particular shade on your bike frame, using an airbrush is worth the extra effort involved.
If you are not as handy with an airbrush gun or don’t need a specific color shade, using spray paint is a great alternative. These are available in ready-made formulas that are compatible with most bikes.
Spray paint cans are already mixed and ready to apply. There is no need to thin the paint or get additional hardware. For instance, there is an attached spray head to eject the paint evenly. Essentially, it is an all-in-one paint job, ready-to-go, and much easier to handle than an airbrush gun.
While using the spray paint, keep in mind the following pointers. The can must be at a certain distance from the frame, so it doesn’t form noses. What’s more, you should keep the can vertical and upright for the best spray pattern.
Another tip is to keep ejecting any paint in the tube of the can before taking a break. Hold the can upside down and keep the nozzle pressed until all the paint is removed. Once no more paint comes out, you can keep it away, ensuring that the spray head won’t stick when you come back to continue.
Furthermore, it is alright to leave a bit of paint when the can starts feeling empty. When spray paint gets to the last few drops, it can cause the paint to speckle. To prevent this, open up a fresh can when the can feels like it’s almost empty.
Steps To Paint Your Bike
Now that you have your materials gathered and have chosen a method of application, where do you start?
Regardless of which method you decide to go with, the steps involved in painting the bike frame are the same. Both methods involve spraying the paint on, so there are little to no differences in the actual application process.
Dismantle The Bike
Preparing and breaking down the bike frame is the first step in giving it a new coat of paint. Only the bike frame needs to be painted, so all the parts that don’t need a coat can be taken off, such as, wheels, cranks, handlebars, and the seat.
Plus, the chain, brakes, derailleurs, and forks need to be taken off too. If there are any more attachments, they need to be removed as well.
Not to forget, labeling and decal on the bike are materials that can prevent the paint from sticking to the frame properly. A heat gun or blow dryer can help in getting these off by heating up the adhesive. Simply scrape them off with a putty knife to lift and peel the edges away.
Make sure there are no spots of glue left on the frame. This can make sanding the frame down challenging and messy. WD-40 is an excellent method to break down the glue and smooth out the surface of the frame.
Sanding And Taping
With all the surface material removed from the bike frame, all that is left is to paint it over. Use sandpaper to strip away the existing paint layer.
You should use compatible grit sandpaper depending on the type of finish the underlying paint has. For matte or plain finishes, high-grit sandpaper will get the paint off with minimal scratches. On the other hand, low-grit or rougher sandpaper is suitable for a thick and glossy paint.
A popular method to control the amount of sawdust is by using the wet sanding technique. Clean off any sawdust and paint flakes with soapy water and allow the frame to dry before moving on.
Other methods of removing the old paint include using a sanding machine. A power tool that significantly cuts down on the physical labor involved in hand sanding.
Additionally, using chemicals to remove the paint is a feasible alternative. However, it does involve the risk of creating hazardous waste in the form of the stripped paint. Ensure you dispose of these wastes in a safe manner.
Furthermore, grease along the frame’s surface should be removed with white spirits or glass cleaner. With a bare, dry frame, the final step in prepping is to tape off the bike.
Taping off the bike means blocking off areas that are not to be painted. These are the bearings, screw threads, and posts for the brakes. As these areas see high friction, applying paint will cause it to chip in no time at all.
Prepare A Workstation
Creating an area to paint the bike is a necessary step not for the paint job but for your own safety and convenience. As is the case whenever working with any paint, ventilation is the crucial factor here.
Ideally, painting the frame outdoors is the most optimal location, but any well-ventilated area will do. Garages, for example, are another great alternative to the outdoors, so long as you keep the door open. Additionally, using a tarp or some newspapers to catch drops and flecks of paint cuts down on cleanup afterward.
Suspend the bike frame in the center of the workspace with enough room to access every angle of it. By suspending the frame, it helps make for a more accessible, even application across the frame.
To get the bike frame in the air, loop a wire or rope through the head tube and tie off both ends to an overhang. This can be a tree outside, a beam, or your ceiling if you’re inside. All that matters is getting the frame suspended.
An alternative to suspension is hanging the bike frame off of a table with a clamp. Use a broomstick, or any tube-shaped object, to attach the frame to a clamp via the head tube. Now the frame is free-standing and can be painted from any angle.
Beyond preparing the workspace, you need to prepare yourself. Get a dust mask to protect you from the paint fumes and a pair of safety goggles before working with the paint.
Preparing The Paint
Depending on the manufacturer’s paint formula, you may need to prime the paint before applying it to the frame. Additionally, if you are working with an airbrush gun, you will need to prep the paint for the gun.
Many paints have no need for a primer as they are an all-in-one formula. However, using primer allows the paint to stick better to the frame. Another benefit of using a primer is evident when using a light color on a dark base.
Mixing bike paint in an airbrush gun involves thinning the paint to get it into a consistency that can be ejected by the gun. Once the paint is thinned enough, it can be loaded into the airbrush gun canister.
Stencils and decals are a way of adding a unique, personalized touch to the frame. These are easy to use and can work with either spray paint or an airbrush gun. Using transfer film is another method of easily adding a decal to a frame.
Painting The Frame
Bike frames call for an even coating of paint throughout its surface as it has a metallic texture. Any clumps or inconsistent paint layers will stand out once the paint dries.
As a result, spraying the paint on is the logical method of application. High-quality spray paint is a straightforward and easy means to achieve this even layering of paint.
Keep in mind the finish and colors involved when selecting spray paint. If you are looking for a color that is not available in a spray can look into using an airbrush gun. Spray paint should never be mixed unless it is from the same brand. Mixing paints can result in an undesirable reaction.
Apply an initial coating on the bike frame to give a base to grip for the subsequent layers. Keep the can moving in a steady motion across the frame for an even layer.
As it is being sprayed onto the bike frame, it is easy to form clumps of paint or “noses” at the tip. To avoid “nosing,” keep the can at a distance from the surface of the frame.
Once you have your base coat down, allow it to dry for 15-30 minutes before applying another coat. Continue this process until the entire frame is completely covered and none of the old paint is showing.
Depending on the formula of the spray paint, the number of layers necessary can vary. Every layer is thin, so it can take multiple passes to achieve a completed look. Make sure you allow each layer to dry for the appropriate amount of time before moving on to another layer.
Apply A Clear Coat Layer
After you have applied the paint to the frame and it has dried, it is essentially ready. However, there is just one final step before the bike can be reassembled.
Applying a transparent coat layer will give the paint a protective surface as well as extend its lifespan. Clear coats are applied in a similar manner to the spray paint.
Hold the can of clear coat over the painted frame and spray an even layer. Allow this initial layer to dry for 15-30 minutes, then apply another layer.
It should be noted that a clear coat does not have a thick viscosity. This means it will be runny and easily forms noses, so don’t panic if you see this on your clear coat layers. Under no circumstances should you wipe this run-off of the clear coat as it will only spread it.
To remove the nosing of the clear coat and any uneven layers, use fine-grit sandpaper. Of course, this will cause the surface of the clear coat to have fine scratches. This doesn’t matter as the subsequent clear coat layer will remove this blemish. Repeat this process until the entire frame has a layer of clear coat.
In total, you should have three layers of clear coat on your bike frame for maximum protection. These layers require proper drying to build up the layers properly.
Drying And Assembly
Now that the bike has been painted and protected, it needs to be fully dry and set. Give the frame a full 24 hours to let the paint and clear coat completely dry. After it is dried, you can remove the tape you applied before.
With the frame’s new paint job, the bike is ready to be brought back to life. Attach all the parts back and securely fasten the screws.
With a fresh, new coat of paint, it is a good idea to invest in a few new parts as well. What’s more, you can match the color of the frame to parts of the bike to highlight or add accents. Whether it is a new handlebar grip or seat, the small touches can add a lot to the look and feel of the bike.
How to Paint A Bike Frequently Asked Questions
1. Is hand-painting possible on a bike frame?
Hand painting a frame can allow for precise designs that are not possible with a spray-on method. It is not widely used as hand painting involves a brush, so the strokes are more noticeable when the paint dries. Additionally, it has an uneven finish.
An alternative to drawing designs is using a stencil or transfer film. Both these methods can give complex designs and are compatible with either application method.
2. Does a clear coat negate a matte finish?
Matte finishes are smooth and do not reflect much light, giving the frame a sleek, low-key look. This effect can be destroyed by the protective clear-coat layer, which is shiny and reflective.
If you are using a matte finish paint, look for a corresponding clear coat spray that is designed for matte paint. These formulas preserve the aesthetic of the matte finish while bringing the benefits of a clear coat.
3. How do I determine how the paint will look on the frame?
There are a variety of paint formulas across manufacturers that have slight differences in hue and shade. As such, what you see is not always what you get when choosing a color of paint for your frame.
To ensure the paint you buy is a suitable color, try applying it on a cheap metal tube or cheap frame. This will allow you to gauge if the paint is the right shade or not.
With that, you now know a bit more about how to paint your bike efficiently.
It is not always possible to get the job professionally done, so why spend extra money when you can do it yourself. Always remember to follow safety guidelines while painting, and don’t rush the process.
Painting bike frames involves many moving parts that make it confusing. So long as you have an idea of what you are doing, you shouldn’t run into any problems.
